Deterioration Sugar Beets Due to Nitrates 39 
size. Their condition was perfect, they had been carefully packed 
and they were crisp, like freshly pulled beets. Apparently no dry¬ 
ing out had taken place. The climatic conditions of the locality 
where these beets were grown are very favorable. The location 
was selected for this reason. There were eleven beets in the sample. 
The analysis follows:

These beets are, according to all the criteria whereby we judge 
beets, of the very best quality, the percentage of sugar is high, 18.24 
percent, the injurious ash is low, 1.67 per 100 of sugar, the injurious 
nitrogen is only 0.16722 per 100 sugar, the ratio of proteid nitrogen 
based on Stutzer reagent is 66.68 percent and on the determination 
of albumin according to Ruempler is 52.6 of the total nitrogen in the 
juice. Andrlik in discussing the ratio of proteid nitrogen to the 
total nitrogen calls attention to the fact that the ratio of proteid 
nitrogen to total increases as the beet ripens and that the proteid 
nitrogen may reach 70 percent of the total in ripe beets with a low 
percentage of nitrogen. The pure ash in the fresh beet is not espe¬ 
cially low, 0.4909 percent, but the phosphoric acid is as high as in 
German beets, which is not the case with Colorado beets, and there 
is no nitric nitrogen. In fact there are only two features in the 
composition of these beets which are common with those of Colo-
